SPECIFICATION forming part of Letters Patent No. 630,789, dated August 8, 1899. Application filed February 17,1899; Serial 705,812; (No model.)

To aZZ whom itJH/CLZ/ concern.- V

Be it known that I, GEORGE E. \VYMAN, a citizen of the United States of America, residing at Walpole, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Paper Boxes, of which the following is a specification.

This invention relates to paper boxes, the object being to provide abox of the knockdown description provided with end-closing flaps of improved construction in respect to their adaptability for so tightly closing the end or ends of the box that granulated substancessuch as sugar, salt, ground coffee, &c.cannpt escape therefrom and become wasted while the filled box is being handled or transported; and the invention consists in the construction and arrangement of a boxblank containing parts or folding sections which provide for making a box having the above-referred-to characteristics and in providing a complete box made from said blank, all as hereinafter fully set forth, and more 'particularly pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective View of a paper box containing end-closing flaps embodying my invention. Fig. 2 is a similar view to Fig. 1,but showing said end-closing flaps in their upstanding positions on the end of the box prior to folding the same to close said end. Fig. 3 is a plan View showing the outside of the paper-blank from which said box is made and showing where on that side the glue or cement is applied for interattaching the parts thereof. Fig. 4c is a section of a part of the blank of Fig. 3, showing the inside of said part in illustration of certain features of the folding flaps.

Reference is had to the drawings, and particularly to Fig. 3, which shows in the cut-out paper-board blank the several side sections and end-closing flaps in flat form and the scored or indented lines between and on which the said sections and flaps turn or are folded in forming up the box. The parallel longitudinal lines 8 and 9, extending from end to end of the box-blank, Fig. 3, are those. on which the end-forming flaps of the box turn inward at right angles to the sides thereof,

as below described. The parallel'lines 2 2 2,

which extend at right angles to said lines 8.

and 9 are those on which the'side sections of the box and the upper end sections turn or fold inwardly; at right angles to the saidside sections in closing the ends of'the'boxl' Referring to Fig. 3, it will be seen that the upper end sections a a, on the upper ends of the side sections A and C, are each of rectangular form and have a length corresponding to the width of said side sections and a width from said line 9 upwardly equal to one-half of the width of said side sections, to the end that whentwo of said sections a shall be folded inwardly over the upper end of the formed-up box the adjoining outer end borders thereof shall be in juxtaposition 'or brought one against the other, as partially shown in Fig.1, when both shall be laid closely against the end of the box, as one is shown to be in said last-named figure. The narrow strip or part E, Fig. 3, on the border of said section D has cement applied to one side at 3, and when the box-blank is first folded to a tubular form said strip is cemented to the outer border of said side section A, thus producing a box-body of rectangular form in cross-section, as shown. On the upper end of each side section D and B and between the ends of said two sections a a are the two infolding flaps 5 of triangular form and 6 6, and these last-named three flaps fold on the lines 5 and 12 12. Said flaps 5 have each a tongue 7 of rectangular form extending from the upper extremities of said lines 12 to a point coinciding with the upper ends of said flaps 6 6, but separated from the latter by two slits, as shown, said slits permitting said tongues, together with the said flaps 5 5, to be folded straight across the top of the box, as shown in Fig. 1, and said flaps 6 6 to be infolded between said flaps 5 and tongues 7 and the outer end or cover sections a a, as indicated in Fig. 1. The said sections prises the two wider sections or flaps J J and the two narrower sections J J on the lower ends of said four side sections of the box. In forming the box-bottom the said wider sections are first folded across the end of the box and their free edges overlap slightly, as shown in dotted lines in Fig. l, in order that there shall be no opening between said edges whereby the contents of the box may escape. The flaps J J have cement then applied thereto and their cemented sides are folded closely against the outer sides of said inner flaps J and have their free edges abutting, as shown in Figs. 1 and 2, whereby they lie across said flaps J, covering their overlapping ends and forming an outer bot-tom section in which the parts are in a common plane. Thus there is formed a strong and tight double bottom for the box. The described means for closing the ends of the box provide efficient means for safely retaining said granular substances without danger of waste in handling and transportation.

\Vhat I claim as my invention is- 1. In a paper box, the combination of four side sections constituting the body thereof, and means for uniting the borders of two of said sections whereby said body is given a tubular, rectangular form in cross-section,

rectangular form thereon, and the sections 6, 6, infolding intermediately of said outer sections and said sections 6, and the tongues thereon, substantially as described.

2. Apaperbox comprisingfour side sections which constitute the tubular body of the box of rectangular form in cross-section, and suitable bottom end flaps, combined with the cover-flaps folding inwardly on the upper ends of said side sections, comprising the outer sections a, a, the inner sections 5, 5, of triangular form each having the tongue 7 of rectangular form thereon, and the sections 6, (i, infoldingintermediatelyofsaid outersections and said sections 6, and the tongues thereon, substantially as described.
